API: Find previous submissions and select one to create and prepopulate a form

Let's say I have 2 forms: form1 and form2. Both have previous submissions. I'd like to build something where I can find all submissions for form1 using a field and place the results in dropbox1, then find a field in form2 submissions and place it in dropbox2. The user can then make a selection in the 2 dropboxes. From these selections, i'd like to use the data in the chosen submissions to pre-populate a 3rd form.

Is there an app that does this? If I have to build this through API, do you have a sample I can copy and modify?

Thanks.

Unfortunately we have no app or widget that can do this. So it looks like you would have to code this behavior yourself.
